I am trying to get the Source SDK running on my Mac and I've come into several problems. First I couldn't find the "games.mak" file supposed to be created when running the script found in the downloaded Github repository. But this seemed to be solved by building all the targets with XCode, after changing some settings. However, I still don't know how to use the SDK to make a game or a mod on Mac. It seems to work differently from the previous game engine I tried, UDK GoW (on Windows), which was quite simple to launch since I only had to create a shortcut to launch the level editor. Here on my Mac with Source SDK, though XCode told me the build succeeded, I can't find an icon for the Hammer Level Editor. I know these are very basic questions, but they are not walked through in the various tutorials I have read so far. Can anyone help?
